The new 8030 series tractors from John Deere include eight models that range from 180 to 355 hp. The biggest innovation in these tractors is Deere’s new PowerTech Plus 9.0-liter engine. Paired with a 16-speed powershift transmission or optional John Deere infinitely variable transmission, the machines pack more power in a maneuverable and efficient package. Models are available in two-wheel drive, mechanical front wheel drive (MFWD), MFWD with independent link suspension, and track configurations.
Deere touts the PowerTech Plus 9.0-liter, 6-cyl. diesel engine as its answer to EPA’s Tier 3 off-road diesel emissions requirements, which take effect in January 2006. Not only do the Deere engines meet the EPA emissions requirements for lower nitrous oxide and soot particulate, they can do so while offering better fuel efficiency and greater power than their 8020 model predecessors. In addition to 43% torque rise capability, Deere claims the 8030 tractors will have 2 to 5% better fuel economy than the 8020s.
Innovations that allow the engine to meet these standards include four valves per cylinder, exhaust gas recirculation, and a variable geometry turbo (VGT) that provides boost at low as well as high engine speeds. Engine efficiency is enhanced with a new cooling package, including Deere’s Vari-Cool fan drive and cooling system. The mechanical-type fan runs only at the necessary speed to meet the cooling requirements of the tractor. This variable-speed design allows for greater efficiency in fuel and power.
Deere also beefed up the 8030s with components that are heavier-duty than those in the 8020s. A new hydraulic system has redesigned hydraulic pump circuits, two filters and a 1,500-hr. service interval. The new system increases hydraulic oil flow at lower engine rpm, which adds responsiveness for all hydraulic functions and improves steering, especially with front dual wheels.
Replacing the smaller Cat. III hitch is a substantially stronger Cat. IV narrow three-point hitch with a convertible Cat. IV narrow (convertible to Cat. III) quick coupler that allows operators to adapt to strip-till or no-till practices that use heavier implements and seeding tools. The new hitch also has a beefier quick coupler.
In the cab, the tractor is very similar to the comfortable 8020 models. There are some tweaks and improvements, though, such as noise-reducing attenuators that cancel out particularly annoying sound frequencies. A wider selection of displays, including a large, intuitive touch screen, also are available for controlling and monitoring precision ag functions in Deere’s GreenStar system.
Prices for the new 8030 tractors range from $118,454 to $216,265. For more information, contact your local John Deere dealer or visit www.JohnDeere.com/Ag.
